    Pull x86 asm changes from Ingo Molnar:
     "The biggest changes in this cycle were:
       - Revamp, simplify (and in some cases fix) Time Stamp Counter (TSC)
         primitives.  (Andy Lutomirski)
       - Add new, comprehensible entry and exit handlers written in C.
         (Andy Lutomirski)
       - vm86 mode cleanups and fixes.  (Brian Gerst)
       - 32-bit compat code cleanups.  (Brian Gerst)
      The amount of simplification in low level assembly code is already

         arch/x86/entry/entry_64.S                          | 197 ++-----
      but more simplifications are planned.
      There's also the usual laudry mix of low level changes - see the
      changelog for details"
